Abstract
A three-compartment, disposable food serving plate includes three ribs in an asymmetric array angularly joined to the bottom and sidewall of the plate. The plate preferably includes a four radius, smooth profile from the bottom to the outer rim and is formed from mineral-filled polyolefin sheet. Mica-filled polypropylene is particularly preferred.

A three compartment disposable food serving plate comprising a substantially planar bottom portion, a sidewall portion extending about the periphery of said bottom portion and projecting upwardly therefrom, a flange portion extending outwardly from said sidewall portion and a divider portion configured so as to segment said plate into three compartments of differing volume, said divider portion having a central junction portion and three ribs extending outwardly therefrom, a first rib, a second rib and a third rib;
- each of said ribs projecting upwardly from said bottom portion and extending from said central junction portion to said sidewall portion, wherein each of said ribs is substantially angularly joined to said bottom portion and said sidewall portion and wherein a first included angle between said first and second ribs differs from a second included angle between said second and third ribs and a third included angle between said first and third ribs differs from said first and second included angles.
A three compartment disposable food serving plate comprising a substantially planar bottom portion, a sidewall portion extending about the periphery of said bottom portion and projecting upwardly therefrom, a flange portion extending outwardly from said sidewall portion and a divider portion configured so as to segment said plate into three compartments of differing volume, said divider having a central junction portion and three ribs extending outwardly therefrom, a first rib, a second rib and a third rib;
- each of said ribs projecting upwardly from said bottom portion and extending from said central junction portion to said sidewall portion, wherein each of said ribs is substantially angularly joined to said bottom portion and said sidewall portion and wherein a first included angle between said first and second ribs differs from a second included angle between said second and third ribs and a third included angle between said first and third ribs differs from said first and second included angles, and wherein further said plate is formed of a mineral-filled polyolefin sheet and is characterized by a profile extending from said bottom portion to the outer edge of the flange, wherein changes in direction of said profile are perpetrated by way of a plurality of arcuate portions, each of said arcuate portions having a radius of curvature and wherein further, the ratio of the length of each of the radii of curvature to the diameter of the plate is at least about 0.02.
A three compartment disposable food serving plate formed from a mineral-filled polyolefin sheet comprising:
- a substantially planar bottom portion;
- a first rim portion extending outwardly therefrom, said first rim portion being upwardly convex and subtending a first arc with a first radius of curvature;
- a second rim portion joined to said first rim portion, and extending outwardly therefrom, said second rim portion being downwardly convex, subtending a second arc with a second radius of curvature;
- a third rim portion joined to said second rim portion and extending outwardly therefrom, said third rim portion being downwardly convex, subtending a third arc with a third radius of curvature, said second and third rim portions forming a sidewall portion;
- and,
- a fourth rim portion joined to said third rim portion and extending outwardly therefrom, said fourth rim portion being downwardly convex subtending a fourth arc having a fourth radius of curvature, wherein the length of said second arc of said second rim portion is substantially less than the length of said fourth arc of said fourth rim portion which, in turn, is substantially less than the length of said first arc of said first rim portion and wherein said fourth radius of curvature of said fourth rim portion is less than said third radius of curvature of said third rim portion which, in turn, is less than said second radius of curvature of said second rim portion and wherein the angle of said first arc is greater that about 55 degrees and the angle of said third arc is greater than about 45 degrees,
- said plate further comprising a divider portion configured so as to segment said plate into three compartments of differing volume, said divider portion having a central junction portion and three ribs extending outwardly therefrom, a first rib, a second rib and a third rib;
- each of said ribs projecting upwardly from said bottom portion and extending from said central junction portion to said sidewall portion, wherein each of said ribs is substantially angularly joined to said bottom portion and said sidewall portion and wherein a first included angle between said first and second ribs differs from a second included angle between said second and third ribs and a third included angle between said first and third ribs differs from said first and second included angles.
